Description

Technical Field

[0001] The utility model belongs to the technical field of floating bridges, and particularly relates to a flexible floating bridge with high structural strength. Background Technique

[0002] A floating bridge refers to a bridge that floats on the water surface by using hulls or floating boxes instead of bridge piers.

[0003] In order to enhance the ornamental and water experience effects, wooden keels and wooden floors are laid on the floating bodies of existing floating bridges, and when a car drives on them, a flexible fluctuation effect can be produced. Currently, this technology has the following disadvantages: (1) If the effect of water surface fluctuation needs to be produced, only wooden keels can be used in combination with wooden floors. When using wooden keels, flexible railings must be used, and the bottom of the flexible railings is connected to the wooden keels. Its own connection structure has low strength and weak impact resistance, and there are relatively large safety hazards; (2) If an overall steel structure, that is, a rigid keel, is used, the existing technology cannot achieve the effect of water surface fluctuation; (3) If a combination of wooden keels and rigid railings is used, the existing technology cannot generate strong structural strength, and the combination strength between the bottom of the rigid railings and the wooden keels is poor, and the effective impact resistance strength cannot be achieved; (4) If a steel structure railing is used in combination with a steel structure keel, the existing technology currently cannot achieve the effective flexible fluctuation effect of the water surface. Currently, in various cultural and tourism projects, there is a demand for such flexible floating bridge projects in many places, but the current market cannot meet the floating bridge technology that has both high structural strength and can achieve the flexible fluctuation effect; therefore, in view of the above problems, a flexible floating bridge with high structural strength of the present technical solution is proposed. Summary of the Utility Model

[0004] The utility model provides a flexible floating bridge with high structural strength. Based on the original structure, a rigid structural framework laid horizontally is added, and adjacent rigid structural frameworks are hinged. The flexible fluctuation function is retained; at the same time, since the railing is connected to the rigid structural framework, and a connecting rod fixedly connected to the rigid structural framework is arranged in the pin of the bottom floating body, the rigid structural framework and the bottom floating body layer form an integral body. The rigid structural framework adopts a rigid framework structure composed of transverse pipes and longitudinal pipes, and has high structural strength; in summary, the present technical solution retains the flexible function of the floating bridge while greatly improving the overall structural strength of the floating bridge and the structural strength of the railing; thus, the problems in the background technique are solved.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] A flexible floating bridge with high structural strength of the utility model includes a bottom floating body layer formed by connecting a plurality of floating bodies arranged in an array through connecting pins;

[0007] A rigid structure frame is horizontally laid on the surface of the bottom floating body layer; the sides of adjacent two rigid structure frames are hinged and connected through a connection structure on the side of the rigid structure frame and an upper connecting member located above the connection pin to form a hinged structure.

[0008] At least one railing is vertically and fixedly installed on both sides of a single rigid structure frame, and the railings between adjacent two rigid structure frames are connected by a drag chain.

[0009] Further, the rigid structure frame is made of rigid pipes, including transverse pipes and longitudinal pipes.

[0010] Further, the rigid pipes are made of high-strength steel pipes, carbon steel pipes, alloy steel pipes, stainless steel pipes, copper pipes, basalt pipes, carbon fiber pipes or aluminum alloy pipes.

[0011] Further, the hinged structure includes an upper connecting member, a first connecting member on one side of the rigid structure frame and a second connecting member on the other side. After the positions are aligned, a coaxial through hole is formed among the three connecting members, and a coaxial bolt is installed in the through hole, so that adjacent two rigid structure frames can perform undulating movements and form an integral body with the bottom floating body layer.

[0012] Further, the positions and quantities of the upper connecting member, the first connecting member and the second connecting member correspond to each other.

[0013] Further, the bottom of the railing is fixedly connected to the rigid structure frame by welding or bolt locking.

[0014] Further, a connecting rod is vertically penetrated and installed in the connection pin.

[0015] Further, the top of the connecting rod is fixedly connected to the bottom of the rigid structure frame.

[0016] Further, the upper connecting member is arranged on the connecting rod.

[0017] Further, a floor layer is laid on the rigid structure frame, and the railing penetrates through the floor layer and is arranged on both sides of the hinge position of adjacent two rigid structure frames.

[0018] The utility model has the following beneficial effects compared with the prior art:

[0019] (1) High structural strength: Based on the original structure, a horizontally laid rigid structure frame is added to the floating bridge; at the same time, since the railing is connected to the rigid structure frame, and a connecting rod fixedly connected to the rigid structure frame is arranged in the pin of the bottom floating body, the rigid structure frame and the bottom floating body layer form an integral body. The rigid structure frame adopts a rigid frame structure composed of transverse pipes and longitudinal pipes, and its own structural strength is high. At the same time, the floating bridge is an integral structure, and the overall strength is significantly improved compared with the prior art.

[0020] (2) It also has the characteristic of flexibility: adjacent rigid structural frames are connected by hinge structures, and adjacent railings are connected by drag chains, which has the characteristic of flexibility. The bridge deck undulates continuously when a vehicle is driving, causing flexible fluctuations on the water surface; it has the characteristic of flexibility while significantly enhancing the structural strength.

[0021] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Specific Embodiment 1:

[0042] Please refer to Figure 1-10 As shown, a flexible floating bridge with high structural strength of the present utility model includes a bottom floating body layer formed by connecting floating bodies 2 arranged in an array through connecting pins 4; in this specific embodiment, the length and width of a single floating body 2 are both 0.5 m; the width of the bottom floating body layer of the floating bridge is formed by splicing eight floating bodies;

[0043] A rigid structure frame 1 is horizontally laid on the surface of the bottom floating body layer; the sides of two adjacent rigid structure frames 1 are hinged together through the connection structure on the side of the rigid structure frame 1 and the upper connecting piece 108 located above the connecting pin 4 to form a hinged structure; as Figure 2 shown, the rigid structure frame 1 is made of rigid pipes, including a cross pipe 101 and a longitudinal pipe 102; in this specific embodiment, the cross pipe 101 spans two floating bodies 2, that is, the width is 1 m; there are nine cross pipes 101 arranged at equal intervals, and the longitudinal pipes 102 are connected between two adjacent cross pipes 101, with nine pairs arranged, and the length of the longitudinal pipes is the same as the length of the floating body 2, which is 0.5 m;

[0044] The rigid pipes are made of high-strength steel pipes, carbon steel pipes, alloy steel pipes, stainless steel pipes, basalt pipes, carbon fiber pipes, copper pipes or aluminum alloy pipes; high-strength steel pipes are used in this specific embodiment;

[0045] The hinged structure includes an upper connecting piece 108, a first connecting piece 104 on one side of the rigid structure frame 1 and a second connecting piece 103 on the other side. As Figure 3 and Figure 8-9 shown, after the positions are aligned, a coaxial through hole 106 is formed among the three connecting pieces, and a coaxial bolt 107 is installed in the through hole 106, enabling the adjacent two rigid structure frames 1 to undulate and form an integral body with the bottom floating body layer; as Figure 3 shown, the first connecting piece 104 is a T-shaped structure in this specific embodiment, and the second connecting piece 103 is a π-shaped structure in this specific embodiment; as Figure 6-7 shown, the upper connecting piece 108 is a T-shaped structure. After the positions are aligned, the upper connecting piece 108 and the first connecting piece 104 are located between the two side plates of the second connecting piece 103, and the through hole 106 is aligned coaxially. After being penetrated by the coaxial bolt 107 as Figure 5 shown, the hinged connection is realized. The coaxial bolt 107 and the through hole 106 are in clearance fit, enabling the adjacent two rigid structure frames 1 to achieve a small range of deflection;

[0046] As Figure 10-14 shown, at least one railing 105 is vertically and fixedly installed on both sides of a single rigid structure frame 1, and the railings 105 on two adjacent rigid structure frames 1 are connected by a drag chain 1051; in this specific embodiment, two railings 105 are respectively vertically arranged on both sides of a single rigid structure frame 1, and a guardrail 1052 is arranged between the two railings 105 on the same rigid structure frame 1. The guardrail 1052 is a steel pipe guardrail in this specific embodiment; the railings 105 between two adjacent rigid structure frames 1 are connected by a drag chain 1051.

[0047] Among them, the positions and quantities of the upper connecting member 108, the first connecting member 104, and the second connecting member 103 correspond to each other; the bottom of the railing 105 is fixedly connected to the rigid structure frame 1 by welding or bolt locking; in this specific embodiment, welding fixation is specifically adopted. Of course, a fixation structure with a flange at the bottom and matching bolt holes and bolts can also achieve fixation, or other fixation methods, as long as the same fixation effect can be produced, all belong to the protection scope of this technical solution.

[0048] As Figure 10-14 shown, among them, a connecting rod 401 is vertically penetrated and installed in the connecting pin 4. For the structure of the connecting rod 401 arranged in the connecting pin 4, the technical solution applied by the applicant has been publicly disclosed. For details, see the appendix in the specification of CN204729432U - connecting pin Figure 3 shown, combined with the Figure 13-14 diagram of this technical solution, the structure of the connecting pin 4 with the connecting rod 401 can be clearly understood. Therefore, the specific structure will not be elaborated in this embodiment; the top of the connecting rod 401 is fixedly connected to the bottom of the rigid structure frame 1. This fixed connection can adopt methods such as welding or fixed connection with a flange and bolts, and is selected based on the applicable scenario.

[0049] Among them, as Figure 13 shown, the upper connecting member 108 is arranged on the connecting rod 401;

[0050] As Figure 13-14 shown, in this specific embodiment, the first fixed connection method between the connecting rod 401 and the bottom of the rigid structure frame 1 and the second fixed connection method between the connecting rod 401 and the upper connecting member 108 are adopted, and the first method and the second method are arranged in an alternating manner; that is, when performing flexible floating, the rigid structure frame 1 and two floating bodies 2 at the bottom are combined into a unit form for flexible floating.

[0051] Among them, a floor layer 3 is laid on the rigid structure frame 1, and the railing 105 penetrates the floor layer 3 and is arranged on both sides of the hinge position of adjacent two rigid structure frames 1; in this specific embodiment, the railing 105 is as Figure 8 shown, and two are respectively arranged on both sides of a single rigid structure frame 1. Specific Embodiment 2:

[0053] As Figure 11-14 shown, the difference feature of this specific embodiment compared with Specific Embodiment 1 is:

[0054] The horizontal pipe 101 straddles a single floating body 2, that is, the width is 0.5 m; there are nine horizontal pipes 101 arranged at equal intervals, the longitudinal pipes 102 are connected between adjacent two horizontal pipes 101, and there are nine pairs arranged, and the length of the longitudinal pipes is the same as the length of the floating body 2, which is 0.5 m;

[0055] The connecting rods 401 are fixedly connected to the upper connecting members 108, and the flexible floating is carried out in the form of combining the rigid structure frame 1 and the single floating body 2 at the bottom into a unit; and the railings 105 provided on both sides of the surface of each rigid structure frame 1 are single and do not have guardrails 1052, and the adjacent two railings 105 are connected by a drag chain 1051.

[0056] Based on the original structure, the floating bridge of this technical solution adds a rigid structure frame laid horizontally, and the adjacent rigid structure frames are hinged to each other, retaining the function of flexible fluctuation; at the same time, since the railing is connected to the rigid structure frame, and a connecting rod fixedly connected to the rigid structure frame is arranged in the pin of the bottom floating body, the rigid structure frame and the bottom floating body layer form an integral body. The rigid structure frame adopts a rigid frame structure composed of transverse pipes and longitudinal pipes, and has high structural strength; in summary, while retaining the flexible function of the floating bridge, this technical solution greatly improves the overall structural strength of the floating bridge and the structural strength of the railing.

The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification.
